For those who have an OBD2 reader (bt, wi-fi, cable) etc., if you ever have patience to check the IAT sensor readings, after a few hours since driving the car, for example, can you, please, share them?
Briefly, I am trying to understand if, after passing many other potential causes, the infamous hot start issues are due to the heat soak of the IAT.
Still, I getting a bit mad as it seems a high reading would lead to a lean mixture and cause all my hot start hiccups.
For example, I measured 50 deg C / 122 deg F, after the car has been sitting for about 5 hours, while ambient temp was 23 deg C / 75 deg F.
Same day, for other three cars, sitting for the same time, on purpose (indeed, different / smaller engines and one was a diesel) but, before starting the engine, the IAT readings were very close to the ambient temp. :banghead:
Every time my IAT sensor reads a temp much closer to the ambient temp, there are no engine starting issues. As the coolant sensor shows similar temps, and the IAT sensor is new, I have excluded any misreading.
